ISO 6947 pdf download Welding and allied processes — Welding positions
This International Standard defines welding positions for testing and production, for butt and fillet welds, in all product forms.
Annex A gives examples of the limits of the slope of a weld axis and the rotation of the weld face about the weld axis for welding positions in production welds.
Annex B provides a comparison of International, European and US designations.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
position of a weld in space, which is defined relative to the slope of the axis and rotation of the face of the weld relative to the horizontal plane
main welding position
welding position, designated PA, PB, PC, PD, PE, PF or PG
NOTE For PA, PB, PC, PD and PE, see Figure 1.
angle of the axis of the weld relative to the main welding position
angle of the face of the weld relative to the main welding position
angle of the axis of the pipe
3 Welding positions
3.1 Main welding positions
The main welding positions are illustrated in Figure 1 with examples of their application for butt and fillet welds in Figure 2.
